A man is being nice to his very own sister. Would you expect him to bad-mouth his sister on national TV? I wouldn’t.
And no way a man could appoint his own family member to a scotus seat. The Congress and people would have a melt down.
(Although they don’t about Bush1, Bush2, Bush3...all from the same family. Thank you N. Korea, the Bushes are close behind.)
Then he should have never mentioned his sister. By sying hissisterwould makea good USSupreme court Justice, he is admitting that he approves of judges who would decide cases much like his sister would.
